Explore the Possible Impact of BCG Vaccination Policy on the Morbidity, Mortality, and Recovery Rates due to COVID-19 Infection.

BACKGROUNDThe Coronavirus Disease-19 (COVID-19) is the new form of an acute infectious respiratory disease and has quickly spread over most continents in the world. Recently, it has been shown that Bacille Calmette-Guerin (BCG) might protect against COVID-19. This study aims to investigate the possible correlation between BCG vaccination and morbidity/mortality/recovery rate associated with COVID-19 infection. METHODSData of COVID-19 confirmed cases, deaths, recoveries, and population were obtained from https://www.worldometers.info/coronavirus/ (Accessed on 12 June, 2020). To have meaningful comparisons among countries mortality and recovery rates, we only choose those countries with COVID-19 infected cases at least 200. The Poisson regression and logistic regression were used to explore the relationship between BCG vaccination and morbidity, mortality and recovery rates. RESULTSAmong those 158 countries with at least 200 COVID-19 infected cases, there were 141 countries with BCG vaccination information available. The adjusted rates ratio of COVID-19 confirmed cases for Current BCG vaccination vs. non-Current BCG vaccination was 0.339 (with 95% CI= (0.338,0.340)). Moreover, the adjusted odds ratio (OR) of death and recovery after coronavirus infected for Current BCG vaccination vs. non-Current BCG vaccination were 0.258 (with 95% CI= (0.254,0.261)) and 2.151 (with 95% CI= (2.140,2.163)), respectively. CONCLUSIONSThat data in this study show the BCG might provide the protection against COVID-19, with consequent less COVID-19 infection and deaths and more rapid recovery. BCG vaccine might bridge the gap before the disease-specific vaccine is developed, but this hypothesis needs to be further tested in rigorous randomized clinical trials.

A Pilot Study: Association between Minor Physical Anomalies in Childhood and Future Mental Problems

OBJECTIVE: This study aims to investigate association between early recognizable minor physical abnormality (MPA) during childhood is associated with mental health problems in young adults. METHODS: In 1984, 169 preschool children in central Taiwan underwent a detailed physical examination for subtle abnormalities (MPA). Fourteen years later, the Brief Symptom Rating Scale (BSRS) and Chinese Health Questionnaire (CHQ) were used to measure specific psychiatric symptoms. RESULTS: There is an association between MPA during childhood and adult characterized with interpersonal sensitivity, anxiety, depression and paranoid mental health symptoms. CONCLUSION: The signs of childhood MPA can be easily identified and should be regarded as risk factors when predicting mental disorder. Mental health professionals should consider MPAs as important signs for possible development of emotional problems.

Postoperative sedation after major surgery with midazolam or propofol in the ICU: effects on amnesia and anxiety.

BACKGROUND: Propofol and midazolam are commonly used in the ICU to alleviate physical and psychological disturbances in consequence of anxiety. This study was conducted to assess and compare the impact of postoperative sedation after major surgery with midazolam or propofol on amnesia and anxiety in conscious patients under intensive care. METHODS: One hundred and two adult patients irrespective of sex and age, receiving thoracic, abdominal or other major truncal surgery necessitating close care at the ICU, were randomly allocated into midazolam or propofol group. Prior to surgery, all patients were subjected to evaluation of the levels of anxiety and amnesia, which was repeated on the following morning with the level of anxiety and the level of amnesia assessed just before and 30 min after cessation of midazolam or propofol medication, respectively. RESULTS: There were no significant differences between the two groups regarding gender, age, types of analgesics used, and anxiety. In both groups, the levels of anxiety (P < 0.001) and amnesia (P < 0.001) were improved significantly over the following day. Midazolam had more pronounced effects on amnesia than propofol (P < 0.001). There were no significant differences between the two groups in the pre- or post-drug anxiety (P = 0.189). CONCLUSIONS: Both midazolam and propofol are effective amnesic and anxiolytic drugs. Midazolam tends to have more favorable effects on amnesia. It is speculated that combination of propofol and midazolam may give better results for treating critically ill ICU patients, the confirmation of which necessitates further study.
